New initrd concept

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi list.

After getting inspired by rich-r/[email protected]'s mail I started work on a
new initrd concept.
Submaster ID: 2005022615304115134

What happens is the following:
mkinitrdnew.sh creates the new mkinitrd named initrdnew-$kernel.img in
the /boot directory. $kernel can be passed as first parameter to
mkinitrdnew.sh.
This script goes then just as the current one through /etc/conf/kernel
and copies the kernel modules not marked with no-initrd to the initrd.
After that it copies default applications and files on the initrd:
- - /bin/bash		# yes, I want to write most of the initrd stuff
			# in bash for simplicity
- - /bin/ls
- - /sbin/pivot_root
- - /sbin/insmod
- - /sbin/insmod.old
- - /bin/mount
- - /bin/umount
- - /usr/bin/chroot
- - /bin/mkdir
- - /etc/fstab

It also copies the necessary libraries for the programs to the initrd
(using ldd to find out which those are).

Last, it goes through the files /etc/conf/initrd/initrd_* and copies
programs to the initrd which other packages (loop-aes will, for example)
have registered. This file has the following format:
<source file>	<target file>

<source file> references a file on the local filesystem and <target
file> the path and filename on the initrd. An example is included.

We might have to increase the default initrd size to 8192 kB, though.
